 ===== ALSA Volume Control =====
-I mentioned above that the **alsamixer** utility can be used to control the output volume levels used for each audio device detected on the system, assuming that your system is using ALSA as its sound server in the first place. If you're using Pipewire or other sound servers, it may not work at all. It also won't do anything if, for example, your audio output is a digital 'sink': when I use a toslink optical out, for example, that simply cannot have its volume modified in software: the laser is either on or off, not dimmer or brighter! Optical out is a good way to isolate your amplifier from electrically-induced noise and digital out by any other means is great if you've got a brilliant DAC (digital-to-analogue converter) you'd prefer to do the heavy lifting, rather than gettting the cheap one in your PC to do it... but abandon any thought of using software volume control if you go these routes: a good remote control for your amplifier will be what you're after!

If you're using Pipewire or other sound servers, it may not work at all. It also won't do anything if, for example, your audio output is a toslink optical out: the light is either on or off, not dimmer or brighter! Even if you use non-optical digital outputs, they're either on or off, so again, varying the signal strength to achieve volume alteration is a non-starter. Optical or digital outputs are brilliant for isolating your amplifier from electrical noise and for when a capable external DAC (digital to analogue converter) does a better job of signal processing than your PC's built-in one... but abandon any thought of using software volume control if you go these routes: a good remote control for your amplifier will be what you're after!
 If you are using a non-digital audio output and the ALSA sound server, however, then you can indeed use alsamixer to adjust music playback volume by software alone. Alsamixer controls one device at a time: you press F6 to obtain a list of //all// audio devices and select one. Once a device has been selected to be the 'active device', you can increase or decrease the volume of that device using the up- and down-arrow cursor keys.
